Tramway or street railway
Warning signsSign no. 1.18OSR art. 10 · art. 93
What the sign says
A tram or street railway crosses the road or runs along it. Its mass and its rails rule out any swerve: it is the one that cannot move aside.
The exam trap
With this sign, the road user must check for themselves that no rail vehicle is coming: nothing will warn them. A moving tram may be passed on the right.

The signs are the official depictions by the Federal Roads Office, from the annexes of the Signalling Ordinance (SR 741.21): official works, unprotected under Art. 5 of the Copyright Act. The explanations, by contrast, are written from federal law — never taken from a third-party catalogue.
